dACQUARD-CARD-PUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 790,126, dated May 16, 1905.

Application filed November 17, 1903. Serial No. 181,527.

T0 all whom, it may cm1/cern:

Be it known that I, HAERYHARDwTcIna citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Jacquard-Oard-Punching Machines, ot' which the following is a specification.

One object of my invention is to adopt, in that class ot machines in which an entire card is punched at one operation, the principle of controlling the punches by means of keys, as in single-row machines, or, as they are commonly termed, piano punching-machines, a further. object being to retain the keys in either class oi machines in either of their positions of adjustment, whereby in punching a series of successive cards or a series of successive rows in the same card only those keys need be manipulated which represent a change from punched to blank or from blank to punched.

In the accompanying` drawings, Figure I is a view, partly in section and partly in side elevation, of sutlicient of a machine for punching a complete card to illustratemy present invention. Fig. 2 is an enlarged section of that portion of the machine to which my invention particularly relates. Fig. 3 is a transverse section on the line a n, Fig. 2. Fig. 4 is a perspective view of part ol the machine. Fig. 5 is a view similar to Fig. Q, but illustrating another form ol' machine embodying my invention. Fig. 6 is an end view ot' Fig. 5 lookingin the direction of the arrow y. Fig. 7 is a transverse section on the line Fig. Fig. 8 is a vertical sectional view illustrating the application of my invention to a machine for punching a single row otl openings at a time in the card, and Fig. 9 is a similar view of another form of such machine. embodying' my invention.

Referring in the iirst instance to Figs. 1, 2, 3, and a ot' the drawings, I. represents the vertically-sliding head of a card -punching machine in which are vertically guided as many longitudinal and transverse rows ot punches 2 as there are longitudinal and transverse rows of holes to be punched in a complete card,

these punches being also guided in a bar 3 and cooperating with the die 4 of the machine, so as to properly punch a card inserted between said bar 3 and the die 4, as shown in Fig. l. Each punch 2 is under the control of a laterally-sliding bolt mounted in the sliding head l oi' the machine, so that when a bolt corresponding to either punch occupies the projected position (shown in Fig. 1) said bolt will on the descent of the sliding head I act upon the punch so as to cause it to 'form an opening in the card inserted between the bar 3 and die 4; but if a bolt is retracted the corresponding punch will on the descent of the sliding head l be unlocked from said head and will be free to rise therein, and hence will not punch the card. rPhe machine may also have punches for forming the lacing-holes and cylinder-peg openings in the card, as usual; but these have not been shown, as my invention has no reference thereto.

One feature of my invention consists in the employment of key mechanism whereby the bolts are controlled, and thus caused to lock or release the punches 2 and determine the punching of the card in accordance with the line of the pattern represented by said card. In order to accomplish this result, each of the locking-bolts 5 has pivoted to it one end ot' a wire 6, whose opposite end is provided with an upwardly-projected hook 7, as shown in Fig. 2, these hooked ends of the wires extending into the laterally-sliding head 8, which can be moved in guides on the iixed frame in any available manner and which carries the keys whereby the control ot the bolts 5 is effected. Each wire has a projecting lug 9, adapted to contact with the back of the sliding head 8 when the latter moves in the direction of the arrow w, Fig. l, so as to restore all of the locking-bolts to their normal locking position. (Shown in Fig. I.) The sliding head 8 carries a series ot' vertically-guided keys IO, each mounted upon a coiled spring Il and each having a downwardly-projecting stem with lug or shoulder 12 and cam 15, the lower end of the stem when the key is depressed being adapted to engage the upturned hook 7 of its corresponding wire 6 and.

8 in a direction the reverse of that indicated by the arrow in Fig. 1 allof the locking-bolts 5 corresponding with such depressed keys will be retracted and the corresponding punches will be rendered inoperative, the remaining punches being locked to the sliding head` 1, so as to form the desired openings in the card.

My invention is applicable -to machines for punching cards for anydesired style-of weaving -in which a jacquard is employed; but-for purposes of illustration I have selected a machine for punchi-ng cards for what is known as a fiveframe Brussels, Wilton, ory like carpet in which the pile-warp threads are in sets of five, one thread of each set or groups of sets being normally operative and each of the other four threads being controlled by a needle of the jacquard machine. card is punched for each of these four needles, therefore, the normally operative thread is lifted; but if the card is a blank for any one of the four needles its corresponding thread is raised and the normally operative thread is rendered inoperative. The keys 10 aretherefore arranged in sets of four each, combined with aidummykey 10a, which represents the normally operative thread and does not engage with any one of the wires-6, but has the lug 12 and cam 15 similar to the keys 10. When any one of the keys is depressed, therefore, its lug 12 is engaged by the bolt 13, and the lower-end ofthe key-stem is held in engagement with the hooked end of a wire 6 until another key 10 or the key 10"L is depressed such action having the eiect of releasing the previously-depressed key and permitting it to rise. If more than one of the keys of a set has been depressed, such series of keys can be released by depression of another key of the set, or by a further depression of either of the depressed keys the others can be released, such further depression of the key bringing its cam 15 into play and forcing back the locking-bolt 13, so as to free the lugs l2 of the remaining keys from control of such bolt. No change in the position of a key is ,required until acorrespondingvpoint on the card is to be changed from blank to punched or from punched to blank. Hence in punching the successive cards only those keys have to be manipulated which represent suchy changes.

In that embodiment of my invention shown in Figs. 5 to 7 the sliding head 8a has rowsl of pivoted keys 10b hung to transverse rods When a1 j ustment.

16 on the head, each key being in the form of a bell-crank lever one arm of which vcarries the key head, whilev the other'arm is hooked, as at 17, for engagement with the hook 7 of a wire 6 when the head of the key has been drawn forwardly in the direction of the arrowvy, Fig. 5, the key being vretained in this position by engagement with a springyoke 18 orequivalent frictional retainer carried by a bar 19, rigidly mounted on the head 8a. When once adjusted to engaging position, therefore, each key remains in position until removed therefrom by swinging it in a direction the reverse of that indicated by the arrow y. l

So. far as I am aware, no attempt has hitherto been made to apply the principle of key control to the punches of a machine for punching a complete card -atfone operation, and my .invention in'its broader aspectV isthereforeindependent ofy mere matter of construction and arrangement ofthel keys or matters of minor mechanical detail, since these may be'- which form only one row of openings at a. time in the card.

The fact thatin my machine ake-y-remains in the position towhich it has been adjusted until a change in the correspondingportion of the card is required f constitutes an improvement upon the ordinary single-row machines in which all of the` keys are restored by springs to normaliposition afterfeach ad- In my machine, moreover, all of the keys are-visible at all times, whereas in the ordinary machine the majority ofthekeys are hidden andare operated by the sense of touch and withoutaid from the sense of sight.-

A simple application of my invention to a single-row punching-machine f is fr that shown in Fig. 8, in which 2u represents one ofthe rows of punches, and 5 locking-bolts for saidV punches, each of these bolts havingat the rear endk a hook 7, which is engaged by-va forked arml portion of oney arm of the key 10C,

the latter beinglpivoted to :the shaft 16. and having two other arms at afright angle tothe forked arm, so that pressure-upon one of said latterfarms will move the bolt 5 into locking position, `while pressure upon the other arm will move said bolt. into unlockingzpositiom.

the friction of the key upon its-pivot-.shaft 16.EL or other frictional y device being: relied upon to keep the key in the position to which it'has been adjusted.

In the construction shown in Fig. 9 the key 10l hasforked armswhich engage the upperv ends of swinging levers-.21, whose'lower ends are therebymoved into vor outof position to..

engage the: arms of4 awlever.` 10c, whiclrengages the hook of albolt 5, as in Fig. 8.

IOO

The keys 10d are mounted upon a fixed structure 2Q above the vertically-reciprocating head of' the punching-machine, and as a key 1()c rises with said head an arm of the key is brought into contact with one or the other of the levers 21, depending upon the adjustment of said levers by the key 10d. In this machine, therefore, the readjustment of the keys 10d can be effected during the operation oi' the punching mechanism-that is to say, while the keys 10C are descending' and again rising-- and more time is afi'orded for effecting such readjustment of the keys than when the keys 10" are themselves directly manipulated, as in the machine shown in Fig. 8. The use of the levers 21 relieves the keys 10d of any strain which would otherwise be exerted upon them by the thrust of' the keys 10. I-Ience there is no tendency vfor the said keys 10d to be displaced Vfrom either position of adjustment. v

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. A jacquard-card-punching machine, having, in combination, a series of' punches for simultaneously punching a number of rows of' openings in a card, locking-bolts for said punches, keys for controlling said bolts, and a key-carrier independent of the carrier in which the punches are mounted, said key-carrier being movable in respect to the punchcarrier, substantially as specified.

2. A jacquard-card-punching machine, having, in combination, a series of punches, locking-bolts therefor, a movable carrier for said punches and locking-bolts, keys for controlling the locking-bolts, and a key-carrier independent of the punch-carrier and lnovable in a direction transverse to the direction of the movement ofE the latter, substantially as specified.

3. A jacquard-eard-punching machine, having, in combination, a series of punches, locking-bolts therefor, a carrier for said punches and bolts, a series oi' keys movable into and out of' connectionl with said locking-bolts, a key-carrier independent of the punch-carrier and means for retaining each of the keys in one of its positions of adjustment on said carrier, substantially as specified.
